Application filed m 11, 1905. Serial No. 269,262.

cago, in the county of Cook and State of Illi nois, have invented certain new and useful Improvements in Adding-Machines, of which the following is a s ecification.

llirily invention re ates to what arecommo y known as adding or calculating machines, which are adapted to add or accumulate and also to record or rint and also list machines being exemplified by the well known Burroughs adding machine, made in substantial accordance with. Burroughss' Patents Nos.

504,963 and 505,078, issued on September My invention has a vplication to that ty e of adding machine w ich has revision Er throwin out or eliminatin t eiadding or accumu ating function of t e machine, so

that the machine is enabled, under certain conditions, or at the will of the operator, to'

rint numbers or amounts without accumuating them and the object of my invention is-to provide a machine of this type withmeans for recording the fact that any par-' ticular number or. numbers haveb'een rinted without accumulation, such result beingaccomplished by printing a suitable indicating character in connection with such particularnumber or'numbers, with the result that the operator is/informed at a glance which numbers or items in the list were accumulatedand which were not.

My invention has useful application to a Burroughs machine to which it may be ap-- lied .as an attachment or an improvement, But it will be understood that my invention is not limited in its application or sco e to such machines, but that it may be empihyed in connection with other machines operating in substantially the same way. andused for.

the same general purposes. For convenience, however, my invention is illustrated as applied to. a Burroughs machine and the same will hereinafter be described in connection therewith without limitation thereto.

In the drawings, Figure 1 is an elevation of the left hand side of a Burroughs machine, in which my attachment or improvements have been incorporated; Fi 2 and 3 detail views illustrating my attac ment in connec-' tion with well known arts of a Burroughs machine; Fig. 4 a detail view of the means a erent denominations increasing .for depressing or shifting the special type carrier from its normal position to a position to rint the total character, and Figs. 5 and 6 ustrations of samples of'work of a machine embodyin my invention.

Inasmuch as 518 construction and mode of operation of the Burroughs machine is so well known, only those parts concerned with my attachment or improvements need be described. For a more detailed explanation of the Burroughs machine, reference may be had to the Burroughs atents aforesaid.

As iswell known, a urroughs adding machine is provided with a keyboard having a lurality of rows of keys"291 representmg from right to left, each row representing the digits 1 to 9. These keys control a series of stop wires 270 which in turn govern the amount ofinovement or oscillation of a series of levers or sector bars 611.- These levers are hung on a main transverse shaft 600 and are operatively connected at their forward ends with sectors 610, the amount of movement of any lever bein dependent upon the value 'of the particulariey o erated 1n the row of keys corresponding to t at lever. These levers carry at their rearward ends a series of movable type plates 618, each bearing type representing two digits. After the amount has been set up on the keyboard and u on the actuation of the main operating sh t of the machine, the levers 611 corresponding to the operated rows of keys will be elevated distances corresponding to the keys operated in their respective or corresponding rows of keys, while the levers 611 corresponding to the rows of keys which have not been Q erated will be permitted to move upwaf' y a slight distanceso as to present the/zero type to its hammer.- Each of the series of levers, which correspond in number to the number of rows of'keys on the keyboard, is provided with hammer mechanism adapted to be driven a ainst any one of the movable type presentef to it, with the result that the particular characteror type whichis presented to the printing line of the platen 1599 will be impressed or rinted upon the paper passed around such p aten,

The hammer mechanism of a Burroughs -machine consists of aseries of hammers 715,

one for each lever 611, whiclihammers'are pivoted upon'a cross shaft 7 O1. mer is provided with a driver 716 having a ch ha will remain laterally projecting stud or pin 7 41 arranged -to cooperate with a slot w in its hammer.

The driver is normally under a tension, by means of the spring 780, to drive its hammer rearwardly against a type plate, but is restrained against such movement by means of alatch 71?, there being as manyof these latches as there are drivers and hammers. These latches, which are pivoted upon the cross rod or shaft 700 are m turn under the control of a corresponding series of awls 718 pivoted upon the cross shaft'or ro 704.- The rearward end of each pawl 718' is springpressed towards its latch and is arranged to enga e the latter unless such rearward end is roc ed upwardly by the contact of its forward end against the inclined or cam surface a of its lever or sector bar 611. Unless the lever has been operated, such inclined surface presented -to,its'pawl, with the result that the latter will be rocked upwardly ferring t and drawn forwardly in the operation of the machine without an eifect u n-its latch 717, and co the'driver' and ammen- When, however, such lever is operated and such cam surface removed from-the path of movement of its pawl 71 8, thelatter will be dpermitted toengageand rock its latch an with and as an incident to the operation of' taking a total. This-result is accomplished by providing the machine with an extra type carrier or lever and an eirtra train ofhammer mechanism, all arrangedatthe right hand side of the series of levers or sector bars 611. These parts 'are under the control of the totalizing mechanism, there beingprovided a rockor oscillating arm, move in the operation of takingatotal, for the purpose of controlling the extra pawl of the train of hammer mech- .amsm,- such arm being provided with a foot arranged to present to such .extr'a pawl an inclined or cam surface correspondinglto that of one of the regular levers, so that t e extra hammer is caused to strike the special type on the special type carrier whenever the totalizing mechanism 18 0 rated and the'rocking arm thereby move to inoperative position, as respects the extra paw in the same manner as the inclined or cam surface of the uent y withou effect. upon thereby release its driven-its hammer to'deliver .the blowby reason of the rearwardrocking of thestud 741f-inthe camw of its hammer.

ter an amount has been set up on the keyboard and the main shaft of the machine operated, the sectors 610 descend distances corresponding to, the value of the keys 0 erated in the rows corresponding thereto, ut at the time of the descent of these sectors the seriesof adding wheelpinions 916 are thrown or rocked out of mesh therewith and remain in that condition 'until just prior'to the ascent or return of the sectors to normal position.

This is accomplished in a Burroughs machine inthe following manner: The series of adding wheels and their pinions 916 are mounted in a rocking frame having sideor-end plates 910, whichare arrangedto rock'upon the cross shaft 900, This frame is arranged to be operatively connected at the proper time to about the: desired rocking movements by means of the reciprocat' lever or pitinan 914 whose forward end iiiiifurcated and anailgd to .e age the rockingframe 910 in the 'usual' an well known manner. The rear endof the itman is pivotally connected with. the depensing arm of a three-arm lever 913, whose oth'e'Ftwo arms are provided with laterally jextending pins or studs. 961 and 961", respectivellfir. This lever 913 is arranged-to be ,osc' ated at every operation of the machine, first in an anti-clockwise direction and then in-a clockwise direction, with the result that the itman 914' is reciprocated first forwardly and then rearwardly', the forward movement of the itman causing a disengagement of the ding wheel, pinions from their sectors and the rearward movement permitting'the return of such pinions to a position of mesh. This oscillationpf the lever 913 is accomplished by the rocking lever 813, which is secured u on the main rock shaft 800, rockedrearwar ly u on the forward movement or roc of t e operating handle, it; such a handle is employed, an

rocked forwardly upon the rearward or return-movement of such handle. The operating-connection between the levers 813 and 913 IS a spring pressed. wipe late 821 pivoted upon the' u wardly' exten ing arm of the lever 813 an arranged to cooperate with the studs 961 and 961 In the rearward or anticlockwise rocking of the lever 813 the wi' e theoperating hand rocks the lever 913 in an anti-clockwise direction, 1, causing the rocking of the adding wheel pinions out of mesh with their sectors. Upon the return or forward rocking of the lever 813, the wipe plate 821 engages the stud 961 and rocks the lever 913 in a clockwise direction thereby shifting the pitman 914 rearwardi and permitting the return of the adding wheel pinions .to'a position of mesh 'in'the well known manner.

' For the purpose of taking-a total at the will of the operator, the pitman 914 is connected with a total key 265, by means of a link 911, so that whenever such total key is-depressed the pitman 914 is shifted to a position so that on its forward stroke and the forward stroke of the handle, it will have no-efiect upon the rocking frame of the adding wheel pinions,

which will consequently remain in mesh with their sectors durin the forward movement of e, at which time'the sectors descend distances corresponding to the total or accumulation represented by the-adding wheels, but such pinions .be removed from mesh with their sectors upon the return movement-of-the operatin handle in case a grand total is taken, with t e result that the adding wheels and pinions will be re-set to zero and ,the machine will .be cleared. If, however, a sub-total is to be taken the total key is released at the end of the forward stroke of the operatin handle, which operation will permit the a wheel pinions to remain in mesh -with 16117866170128 and the end sub-total, which has been rolled off or transferred from the pinions, will be rolled back upon the latter.

In the usual Burroughs machine, the total k e de ending arm connected by means of a link 226*with a roc frame ha side or lates 219, carrym between t em the usua universal rod or re ease bar 202, which is concerned in the operation of releasing or re-setting. the keys on'the keybo fld. Whenever, t he total keyis-depressed, the pitman.

914 is controlled or' shifted' and at the same time any keys which may have been operated are-released.

The Burrou hs machine asherein shown, Fig. 1, is provided with means for throwing 'out or eliminating the adding feature or function of the machine, such means, in the present instance, consisting of a swingin or rocking bar or lever 1, which is ivote at its rearward and upon a fixed stu or pin 2, machine.

rojecting from the frame of the This'bar or -lever is operatively connected with a verticallf}; movable stem 3 of a s ial key 4 at the le hand side of the ke bird and such bar is sopositioned as to lie projected or depressed into the path of movement of the wipe plate821, whenever such special key is operated or depressed. The result of this interference with the wipe plate is connected gith a bell crank 227 whose roughs -machine is provided with the socalled star attachment for the printing of a star or other designating character as an incident to the operation of. taking a total, but such attachment is somewhat modified in order to accomplish the purposes of my invention. Referring to 2, the special type carn'mr orlever 611is pivoted upon the usual fixed late 723 at the point 723 and provided wit a pin and-slot connection therewith. In the present instance, this plate is provided with a transverse slot 723 to receive the stud or pin 611 projecting laterally-from the'extra or special type carrier 611. This s ecial type carrier is provided with a movabde type late 618" having two type, the upper one oi which, marked 618", is the indicating character for the total, the same being, in the present instance, a star, while the other type marked 618 is the character for indicating the fact that the accumulating function of the machine was eliminated or thrown out at the time any particular item was printed. In the present instance, this latter character is a double cross as shown in the sam le of work in Figs. 5 and 6, but as will be undbrstood, any other .form of character for the purpose as distinguished from the star em loyed.

ormally, the indicating character 618 is presentedtowards the printing line of the platen, as indicated in Fig. 2, the same bein spring pressed to this position, but arranged to be epressed so as. to present the star character, may be character to the'printing line whenever the totalizing mechanism is operated To this end, the. specialty e-character is provided with an arm 5 who extends upwardly just in the rear of the rock shaft 207, which extends between the side'plates or frame 219, already described, For the purpose of rocking the arm 5 and thereby depressing the specialty e carrier 611, whenever the totalizingmec anism is operated, the rock shaft is provided with present instance, is in t e form of a bent in 6, normally bearing against the forward e ge of the arm 5 and arranged to rock such arm rearwardly against the tension of the spri 7. One'end of. this sp" arm 5 and the other rid to the plate 723, with the result that the special type carrier is held with a yielding pressure, to the noris fastened tothe l mal position indicated in Fig. 2.- Thus, in the act of taking a total, thespecial ty e carrier is automatically depressed by the pro or setting of the totalizigg mechanism, 1 so t at the star will be rint in the 0 eration of printi thetota and as an inci ent thereto. It W1 1 'be understood that the hammer mechanism belonging to the special ty e carrier is 0 rated in a manner which is wel known an it will, therefore, suffice to state that whenever the tot mechanism is operated the cross shaft 20.6 is rocked in an anti-clockwise direction, Fig. 2 with the result that the de ending arm 8 which is secur such-roe shaft and provided at its lower end with-a foot resenting an-inclined or cam surface 8, be swu or rocked.

upwardly out of the .range of t e forward end or tail of the special pawl 718', whereupon the 's ia'l latch 717, together with t 0 special 'ver 716' will be tripped and thes ial hammer 715 will be -dr1ve'n against t emovable type 618,;

The special type plate is normally in osition to permit of the special (ills:- acter 618and t e special miner-"mechanism is caused to operate asian incident to the printing of aii'amount after the depres'-- sion of the. special key 4, for the purposeof e'adding or accumulati function of' the machine. To accomplis -;this result, I provide anoperatins connectionbetween the stem of the speci k'e 1 4 and the rock shaft 206 which is cause a swinging of the dependingarm 8 in the same manner as the depression of the total key, but without causing-a rocking of the shaft I 207 forming part of the key're ease mechan-' ism. In the present instance, the usual arm 227} which is secured to, and depends from, the shaft 206 on .the left hand side of the machine, is provided with a forwardly extendcial key ing arm whose free end is upturned so as to present its e to a pin or stud 3 projecting. laterall om the stem 3 oflthe spe- 4.- This arm 9 is normally spring presse against such in with a yielding ressure as by means 0 the spring 10, wit the resu t that the parts now be, described are kept in the normal position in icated in Fig. 1. The de nding 327}, instead of being pivota y conneete 'th the link 226 as heretofore, so as to move at alltimes in unison with such link, is arranged to be moved or rocked-rearwardly by the link and also to have a movement independent thereof, whenever the special key 4 is o ted. For this .urpose a stud or" in 250 which rojects aterally from theli' 226, instead 0 having a pivotal connection with the depen 22.71- is arranged to pressagainst thee oul-,- deredend ofthe latter so as to move the same -a-' rm .v in the operation of taking a total the dethat direction wheneverthe special. key 4 is de ressed.

ft is now evident that whenever the special key 4 is operated the adding function of the machine is thrown out by the projection of the bar or lever 1 into the path of movement of the wi e plate 821 and at the same time throu h die medium of the arms 9 and 227}, the epending arm 8 is rocked rearwardly, with the result that when the amount set up on the keyboard is printed the special.

designate by aprinted characterthe' item or,

items 'which'h'ave not been-accumulated, so that the operator may tell at a glance at the list the particular items which were simply printed without accumulation and ted recordof theffact.

arm 8 is not only moved in the manpend? nor an for thepurpose already described in connection with the print' of the s ecial designating character, but t e specia t carrier 6.11, is depressed so as to resent t star character to the printing ne of the latan, as seen in Fig. 3, so that such star will rinted in connection with the total. ccordingto the present and herein described construction, the'machine is capable of printing thetotal character, that is the star, whenever the totalizing mechanism is set for taking a total'and the machine operated, whether. the machine is clear or not,-with the result that the star alone may be rinted, which, if-p'rinted at the head of a co umn or list of items, may be taken as indicating the fact that;v the machine was clear when that list wasstarted. In like manner, the special the machine, after,-

may have character for indicating the non-accumulating condition of the'machine'niay be printed alonegwhenever the. special key 4 is depressed and the'fm'achine operated, the special character thus affording a printed record of the-fact-that when the machine was 0 erat'ed'theaeeumulating function or meclij anisinof the machines. thrown out or igo rendered giriiiperativewhether an it m or number wasprinted' y 'the machine or not.

' machine embodying m invention finds ,useful "application for classes of accountant fwork; wherever it is w I to print in -a list or otherwise, that ifferent is .hesamecolumn-or different columns,

- of the particular clerk total of the same which is $10.90, being theret rough.

amounts or items, some of which are accumulated and some of which are not, my special designating mark indicating and making a record of the fact that the particularitem in connection with which it is rinted was not accumulated; Such a mac ine is par? ticularly useful in large stores em loying numerous clerks who ar'eknown y certain numbers and the record of whosesales are separately printed on sheets with the number of the particular clerk at the head of the list of items representing his sales. It is desirable to em loy the adding machine to print the number of the clerk at the head of thelist or column, but such number, of

" -course,'is one which should not be accumu-- lated. A-sample of the work of this particular class is illustrated in Fig. 5, which example shows, by means of the star, that the machine was clear when the list was beginndou le and the number 248, by reason of the indicates .the number whose sales are listed below, and also indicates the fact thatthis cross markv following particular' number was not accumulatedl.

As stated, the succeeding items represent the sales made by .thatparticularclerk a'nd, thefa'ct that no exponent or indicating char- I acters follow these particular items, indicates that the same were accumulated, the

indicatedbythe footing, hich is followe by the star indicating suc total. However, my improved machine may be used 'for quite different/ classes of work. and'for somewhat different purposes. -For"instance, asvshown in the example in Eig.' 6, thesamej maybe employed to indicate the fact that any par- 'ticular number or. item' of a list of items, -whether such particular number occurs at -the top or any other place in the list, has not been accumulated or rather has been eliminatedfrcm such list When, as sometimes occurs,-the operator discovers that he has set 'up the-wrong amounton the ke board and makes such discovery after 'heas started the operating handle forward, it is possible, to eliminate 'such item,fsc far as accumula-.

tion is concerned, by thereupon immediately depressing the s cial-ke 4, and completing the operation the mac 'ne, which will result in throwing out the accumulating mech-- anism and printing 'the specialcharacter adjacent such item. This character thus indicates that this particular item was not accumulated. and the operator is thereby relieved of the necessity o passing the complement of the 'item through the machine in the well known wayand of canceling the item, as is usuall done by drawing a encil or pen According to e exam le of Fig; 6, the operator set up on the ke board the item 4.35, whereas the itemsho d have been 4.55 but, discovering his mistake be- A described.

fore completing the operation of the ma chine, and before the item has been printed (but after the handle has been startediforward which prevents resetting of the keyboard) the special key has been depressed and the operation of the machine completed,

with the result that, while the wrong amount has been printed it is followed by the s ecial character indicating that the same as not been accumulated in the 'machine- The operator thereupon 'sets u the correct amount. on the keyboard, whichis 4.55 and proceeds with his work.
